      ARM: OMAP2+: Disable code that currently does not work with multiplaform · a62a6e98
      Tony Lindgren 提交于
      We still need to fix up few places for multiplatform support,
      but that can proceed separately. Fix the issue by making the
      problem drivers depends !ARCH_MULTIPLATFORM for now.
      
      The remaining pieces that are not multiplatform compatible
      for omap2+ SoCs are:
      
      1. Some drivers are using custom omap_dm_timer calls
      
      There are two drivers that are directly usign omap hardware
      timers for PWM and DSP clocking: drivers/media/rc/ir-rx51.c and
      drivers/staging/tidspbridge/core/dsp-clock.c. These can be
      fixed for multiplatform by allowing a minimal set of hardware
      timers to be accessed, and for some functionality by using the
      hrtimer framework.
      
      2. Hardware OMAP4_ERRATA_I688 needs to be fixed up
      
      This can't be enabled for multiplatform configurations in
      it's current form. It may be possible to fix it up to do
      instruction replacement early on during init. Luckily it
      looks like this errata does not seem to get hit with
      mainline kernel code alone at least currently.
      
      3. Legacy header needed for omap-sham.c
      
      Looks like it still needs mach/irqs.h for omap1 that
      does not exist for multiplatform systems. Just ifdef
      it for now.
      
      4. Mailbox is waiting to get moved to drivers
      
      Disable it for now to avoid adding a dependency to the
      mailbox patches.

      ARM: OMAP2+: Add multiplatform debug_ll support · 808b7e07
      Tony Lindgren 提交于
      Add multiplatform debug_ll support by stripping away
      the custom hacks to detect the port from debug-macro.S.
      
      Note that this now requires the specific debug_ll port to
      be selected in the .config.
      
      The old debug-macro.S will be removed a bit later
      once we are sure things work properly with multiplatform
      enabled.

      We only want this initcall to run when the kernel is

      We need to make sure that multiplatform kernels don't
      run omap initcalls when booted on other SoCs.
      
      Do this by adding wrapper macros for the initcalls that
      return early if soc_is_omap() test fails. This allows
      us to easily change the defines later if we have SoC
      specific init sections available.

      ARM: drivers: remove __dev* attributes. · 351a102d
      Greg Kroah-Hartman 提交于
      CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
      markings need to be removed.
      
      This change removes the use of __devinit, __devexit_p, __devinitdata,
      and __devexit from these drivers.
      
      Based on patches originally written by Bill Pemberton, but redone by me
      in order to handle some of the coding style issues better, by hand.

      ARM: nomadik: bump the IRQ numbers again · d9621176
      Linus Walleij 提交于
      Bump the IRQ numbers from offset at 1 (right above NO_IRQ)
      to 32. This is the painful way to learn that if you're using
      SPARSE_IRQ and avoid to define .nr_irqs in your machine,
      the first 16 IRQs will be pre-allocated, and the IRQdomain
      code (as the VIC core code before it) will then assume
      that all IRQ descriptors are pre-allocated, and 16 of them
      are - by somebody else. So mapping the IRQs will fail in
      irq_create_mapping(). Moving the offset upward rids us of
      this problem.

      All boards, except Amstrad E3, mark USB config with __initdata.
